IMPROVEMENT IN TANKS FOR WATER-CLOSETS.

Specification fox-iningpari o1 Litters Patent No. 149,746, dated April14,1874; application filed March 11, 1874. I

To all whom it may concern Be it known that I, JAMES GRIFFITHS, ofDeptford, in the county, of Kent, 'England, have invented a certain newand useful Improvement in Water-Tanks, of which the following is adescription sufficiently full, clear, and exact to enable any personskilled in the art or science to which my invention appertains to makeand use the same, reference beinghad to the accompanying drawing,forming a part of this specification, in which-.-

Figure 1 is an elevation of my improved tank with the side broken out toshowthe arrangement of the compartments and valves. My invent-ionrelates more especially to that class of water-tanks which are used forsupplying water-closets and sinks; and consists in a novel constructionand arrangement of the parts, as hereinafter more fully set forth andclaimed, by which a more effective and economical apparatus is producedthan is now in common use.

The extreme simplicity of my invention renders an elaborate descriptionunnecessary.

In the drawing, A is the main tank, which is divided transversely by thewalhlt to form the small tank B, having the sub-tank 0 formed by thefalse bottom S. WVithin the main tank A there is also a compartment, T,opening into the tank B by means of the aperture 0. The tank A isprovided with an ordinary cap-valve mechanism, G M, opening into thechamber T, and connected by the chain 1? with one end of the valve-leverH.

The chamber B is also provided with a capvalve mechanism, F L a, but ofgreater capacity, opening into the chamber 0, and connected by the chainN with the opposite end of the lever H. A The tube D is for supplyingFrom the foregoing the nature and operation of 'my invention will bereadily understood by all conversant with such matters.

In tanks of the ordinary construction, a

great waste of water frequently occurs by accidentally or purposelyleaving the pull on or the valve open.

There is also no' provision for flooding or washing the basin of thecloset after the pull is released, difficulties which are entirelyobviated by my invention.

The lever H is provided with a weighted or gravitating end, at, whichcauses that end of the lever to fall when the wire J is released, thusclosing the valve F L a, and opening the valve G M b. The last-namedvalve be ing open, water from the tank A will pass into the compartmentT, and thence through the aperture 0, and fill the tank B. If, now, thewire J is pulled downwardly, the valve G M b will be closed, shuttingoff the water from the compartment T and tank B, opening the valve F La, and filling the chamber or subtank C.

It will be seen that, when the wire J is pulled and the valve F L aopened, the water filling the tank 0 will be discharged through the pipeE, air passing into the tank through the tube D to supply the vacuumthus caused. The valve F L a is of greater capacity than thedischarge-pipe E, so that when the valve is open water will be passedfrom the tank B to the sub-tank G faster than it is discharged from thesubtank by the pipe E. Thus, when the valve F L a is closed, byreleasing the pull attached to the wire J the water in the tank 0 willbe entirely discharged to wash the basin after water has ceased to passfrom the tank 13 into the tank 0.

It is important, usually, that water should be supplied to water-closetsand sinks very rapidly, and in quite large quantities. It is alsoequally important that it should not be wasted. For these reasons, Iprovide the tank B with the sub-tank O,having the large airpipe D. Whenthe wire J is pulled, the contents of the sub-tank C will be veryrapidly discharged; but, if the wire is not released, or the pull isaccidentally left on, the valve Gr M I) being closed, no more water canbe wasted than what is in the tanks B C at the time, as will be readilyobvious, thus preserving the contents of the main tank A.

Hence it will be seen that by my improvement the proper quantity ofwater is measured out from the tank B, thus preventing all waste,

and at the same time furnishing a means of compartments T B C,Va1ve G MZ), lever B, rapidly supplying water to the sink or closet, pipe D, andvalve F L a, combined to operate as desired, and also of washing thebasin of substantially as and for the purpose set forth the closet by adischarge of water after the and specified.

pull is released. JAMES GRIFFITHS Having thus described my invention,what itnesses:
